The Sound Barrier

Watch the first 25 minutes of "The Right Stuff". The DVD is in the machine--just press play. You will see the story of Chuck Yeager and the Bell X-1, the first supersonic plane. You can stop the DVD just after they say on the ground "We did it! We broke the sound barrier."

Lift and Drag

• Find the four kinds of wing shapes, and take a screenshot of each at a 12 degree angle of attack. (Example here.)
• Circle the Lift and the Drag, and compare them for the different shapes.

ST: Forces of Flight

Remember when you get to question 6:

• "Dynamic Equilibrium: When forces are balanced and speed is steady/unchanging"
